I IMPROVED LOCOMOTIVE-TBNDER LOADER The Schedule :eferred to in these Letters Patent and making part of the same.

To all whom it may concern.-

- Be it known that I, ALBERT H. SPENCER, of the city and county of Providence, and-State ,of Rhode Island, have invented a certain new and useful Locomotive-Tender Loader. 7 i

My invention relates to the construction of a hoisting apparatus for elevating fuel or water into a locomotive-tender, and in' having the same so arranged, with relation to the locomotive, that the labor of hoisting shall be acconn'ilished-by its tractilepower; and 1 do hereby declare that the following specification, taken in connection with the drawings furnished, and

description thereof.

. The drawings represent, in perspective, a locomotive and tender, with my invention clearly illustrated.

A representsthe water elevator. It is a derrick,

extends at such distance beyond the upright as will admit of leverage by the hoisting-chain, and'cause the arm -to swing toward the tender. This arrangement of the derrick-arm constitutes one feature of my inembrace within its sweep a well, reservoir, tank, or stream, whatever the source of immediate water-supply may be, and alsothe tank in the locomotive-tender. In the drawinga well is shown. The slight inclination of the upright toward the well secures an easy swing of the arm back from the tender to the well.

B is an elbow-lever, pivoted at its corner to the under side of the denick-arm, near the upright. Its lower end is arranged, when the derrickarm is parallel with the track, and toward the well,.to pass between two projecting rods in the upright, marked 0, the oband prevent, until desired, the swinging of the arm. A chain and bucket (the latter provided with suit-able discl'iarging device) are'attached to the derrick, in an obvious manner. A short distance above'the bucket, 21. cross-bar, D, is secured to the chain. The. bucket, on being hoisted, continues its vertical course until the bar 1) comes in contact with and lifts the projecting arm ofthe lever B, disengaging its lower end from the rods 0, and permittingthe derrick-arm, with the bucket, to swing toward the tender.

E represents a sclt operati'ng brake, arranged upon a block, over which the hoisting-claim passes. This brake is linked to a staple at one end, and, at the other, passes through a large staple, the upper end of which inclines in the direction taken by the chain during the process of hoisting. The outer end of the brake-lever is provided witlra suitable weight. This brake also constitutes a feature of my invention. Its operation is obvious. As the chain is being drawn for hoisting, the lever, resting on it, is swung to the upper part of the inclining staple, and thereby, in a measure, relieves the chain from pressure. When the chain is let go for lowering the bucket, the lever is carried backward, pressing downward upon the chain, and preventing it from moving too rapidly.

We will now proceed to the description of the fuel- 'elevator, marked G. It is obvious that asimilar der- -rick to that already described could be made to serve an excellent purpose in the elevation of fuel, as well as water. I prefer, however, an apparatus as described. The fuel-elevator is provided with a frame-work, consisting of two uprights, and a cross-bar on top.

H H are vertical and curved slides, secured to the inside of the uprights, and are each provided with a groove on their inner sides.

I is a fuel-car, and can be made in any desirable form. Ipreferth'e form shown, which can be well described as at box bod. This car is provided with two pintles, one on each side, which are arranged toeugage with the grooves described in the slides H H. A swinging bail is attached to the sides of the car, towhich the hoisting-chain is connected. A brake, like that already described, should be attached to the fuel-elevator, to regulate the lowering operation.

The hoisting being done by the locomotiveas' it moves on the rails, it is desirable to provide a means of disconnection between it and the hoistingchains, which shall be under the control of the engineer while in the cab. My invention also relates to such means, and they are next described L is a shaft, extending across the platform at the front end of the locomotive. It is secured in suitable bearings. its outer ends are curved to serve, when turned forward, the'purpose of a hook. Atany desirable point on this shaft a crank-lever is attached, to which is secured a rod, M, which extends to the-cab of the locomotive. By operating this rod back and forth, the shaft L is partly rotated, and its curved ends so operatedv as to turn backward or forward.

Having thus described my invention in detail, it-is only necessary to describe its general mode of operation.

The bucket being in the well, and the fuel-car adjusted to the slides and loaded, we will suppose the locomotive to be slowly approaching the station. An assistant attaches, by a hook or ring, the hoistingchains to the hooked ends of the shaft L, and the locomotive, in its progress, hoists one or both. The waterbucket is hoisted vertically until the lever B permits it'to swing toward the tender. The fuel-car rises in the slides until the proper height has been attained, when pins in the front outer edge of the ear engage with the under side of the slides, and cause it to tip forward and discharge its contents into the tender, which, by this time, will be directly opposite, the length of the l'ioisting-chain being determined in such a manner as to accomplish that object. The water-bucket may be discharged by a suitable valve, which I prefer should be so constructed as to admit of the. filling of the bucket in the well without tipping. Upon being discharged of their contents, the engineer, at the proper moment, pulls on the rod M, and, by rotating the shaft L, disengages the lmisting-chain, allowing the bucket and car to descend, the fuel-car being controlled by the slides, while the water-derrick, on being released from strain on the chain, swings, by reason of its inclination, before described, back in direction of the well. As the available hoisting power is practically equal to any requirement, any reasonable quantity of fuel or water may be thus elevated.

To secure a draught of water from a deep well, it is only necessary to arrange drums and Windlass in an obvious manner, so that the movement of the locomo-' tive twelve inches, for instance, might effect a hoisting movement of several feet, or the draught-pulley may be set at any requisite distance from the well.

lilavingthus fully described my invention,

1 claim as new, and desire to secure by Letters Patent- L 1. The herein-described method of supplying locomotive-tenders with fuel or water, which method consists in using the traction of the moving locomotive,

acting through chains, or any proper connection, to raise the buckets, boxes, or other delivering apparatus, so that their contents may be discharged into the tender, substantially as set forth.

2. In combination with a hoisting apparatus, the lever B, operating substantially as described, for the purpose specified.

3. In combination with a hoisting apparatus, the self-operating brake E, arranged to operate substantially as described, with relation to the hoisting-chain, for the purposes specified.

4. The combination of the fuel-box or water bucket with the elevating-chain and shaft L, or its equivalent, for the purposes set forth.

5. For use in combination with a suitable hoisting mechanism, and attached to a locomotive, the shaft L, arranged to readily attach to and be detachable from the hoisting-chain, substantially as described.
